Abstract
A pair of canards (18, 20) are mounted to the fuselage (22) of an aircraft (10). Each canard is mounted to the fuselage by a hinge (44) for vertical swinging movement. Connected to the hinge (44) is a trunnion (72) about which the canard rotates for incidence adjustment. The hinge (44) for each canard is independently powered by a drive motor (58) enabling the canards (18, 20) to be vertically moved either symmetrically or asymmetrically. Incidence is changed by a rotary actuator housed within the trunnion (72) for each canard. The rotary actuator for each canard is independently operable enabling the canards (18, 20) to be symmetrically or asymmetrically rotated.
